Earlier it was stated that three factors check population growth. These are predation, disease and insufficient food supply. For much of our history, our ancestors’ numbers were indeed limited by wars, disease and famine. The world population remained relatively stable until around 300 years ago. Then at the beginning of the 19th century (100 years after population growth started its geometric increase), the demographer Thomas Malthus predicted that population growth would outstrip food pro

Charlie Chaplin - Table Top Ballet This is a one-minute clip from the silent film era of Charlie Chaplin entertaining four women using two forks and two dinner rolls as a kind of puppet to create a ballet of sorts. The action is set to classical music and is very funny - a great example of Charlie Chaplin's humor. (01:02)Author(s): No creator set

Section 32 of the Scotland Act provides that a Bill, once passed, must be submitted for Royal Assent. This is done after a period of four weeks. During that time, the Bill may be subject to legal challenge by the Advocate General for Scotland, the Lord Advocate or the Attorney General, and may also be subject to an order made by the Secretary of State. The Presiding Officer may, however, submit the Bill for Royal Assent after less than four weeks if notified by all three Law Officers and the

Collecting seashells on an Ordovician beach would have been a rather curious experience. Whilst most shells were made of similar materials to those found on a modern beach, the detailed form of many would have

When you are absolutely sure that you know what the diagram or table is all about, start to look for patterns, for discrepancies, for peaks and troughs, for anything unusual. Diagrams and tables are highly patterned information, and they often tell a relatively simple story underneath. Don't get bogged down in the relationship between individual numbers, but look to see whether one relationship is like another, or whether one set of numbers stands out significantly from the rest.

For each use case there may be more than one scenario. In the process of requirements elicitation and specification, you may find a certain amount of common behaviour in two or more of your use cases. You may even find that an existing component can provide part or all of that common or shared behaviour. Indeed, if you do find such an existing component, this is an example of reusing requirements which is discussed more fully in MRP.

Anti-social behaviour, homelessness, drugs, metal illness: all problems in today’s society. But what makes a problem social? This unit will help you to discover how these issues are identified, defined, given meaning and acted upon. You will also look at the conflicts within social science in this area.

The Arts Past and Present: Mosaics How can we read an image to tell us more about its ancient maker?

The term ‘phenomenology’ is a good example of polysemy, as it has different meanings according to the academic context in which it is found. There are scientific phenomenology and philosophical phenomenology, for example, and the sociologists Ken Thompson and Kath Woodward describe phenomenology as, ‘The development in sociology of a philosophical approach which focuses on people’s consciousness of their experiences and how they interpret the world; the meaning it has for them’ (Tho

These have no binding force and therefore are ineffective as Community law. However, they can have ‘persuasive authority’. If a recommendation or opinion is ignored, it may later be followed up with a stronger legislative initiative, such as a decision or directive.

The first principle in planning is: be clear about your own direction and purpose – in other words, your values and why you are doing anything. You can use the technique of asking why? And then why? of the answer. And then why? of the answer to that. Keep repeating this process until you get back to your underlying values to create an objectives tree or network to help you define the direction in which you wish to go and the steps necessary to get there.

In the saturated hydrocarbons, whose structural formulae are shown in Figure 16, it is not possible to form distinct isomers with just three or less carbon atoms linked together. There is only one way in which one carbon and four hydrogen atoms can be linked together, the single compound being methane, CH4. A simila

The phenomenon of scattering was an important topic in physics long before the development of wave mechanics. In its most general sense, scattering is a process in which incident particles (or waves) are affected by interaction with some kind of target, quite possibly another particle (Figure 1). The interac

If you were to set up a newsagency business on your own as described in Activity 2, you would be a sole trader. Often this is described as being ‘self-employed’. You would be the ‘owner’ of the business. Whilst other people might be involved in your business (for example, as employees or suppliers), it would nevertheless be your business
